Abstract: Abstract of the Disclosure A releasable, high-pressure seal is formed between axially aligned conduits each fitted with an end flange.  One of the end flanges is relatively rigid.  The other end flange is relatively resilient and slightly frustoconically shaped.  The periphery of the resilient flange is connected to its associated conduit.  A seal ring is disposed between the two flanges in proximity of the opening through the flanges.  Fluid pressure applied to the inside of the resilient flange biases that flange towards the rigid flange because the portion of the former radially outward of the seal ring is subjected to ambient pressure only.  In this manner the sealing force applied against the seal ring is increased proportionally to the fluid pressure interiorly of the conduits. A pair of opposing, inner conduits are rigidly secured to the respective outer conduits and they protrude past the outer conduits.  They engage each other first when the conduit sets are axially moved towards each other so that the inner conduits act as a centering device.  A seal is placed between ends of the inner conduits and the conduit sets are secured to each other with a peripheral clamp engaging opposing peri-pheral collars of the outer conduits.

Abstract: ABSTRACT OF THE DISCLOSURE         An automatic hue control system is provided for a color television receiver.  The system uses a single sampling of a vertical interval reference (VIR) signal to establish the hue setting of the receiver.  The VIR signal periodically appears during a pre-selected line in the vertical blanking interval of a broadcast video signal. The VIR signal includes a chrominance reference portion of such phase that one color difference signal is zero, and also includes another portion having no chroma content. Sampling of the VIR signal during at least part of the chrominance reference portion and AC coupling in a control loop enable the loop to respond to any transition in the one color difference signal between chroma reference times and no chroma times.  Any such transition is used to correct The hue setting of the receiver.

Abstract: ABSTRACT OF THE INVENTION           A pair of identical strap elements are provided, each of which comprises a first substantially planar rectan-gularly shaped end portion which is notched along its opposite edges to receive the inwardly turned edges of a channel member to which the pipe is to be clamped, a concave mid-section con-forming with the curvature of the pipe and a planar opposite end portion which is initially formed with rectangular corners, but one of which corners is punched and bent inwardly at a right angle to the plane of the planar end portion to form a tab.  The configuration of the punched-out tab is such as to provide a hooked end with the hook directed downwardly toward the concavity of the mid-section and an arcuate ramp leading to the cut-back in the end which forms the hook.  In addition the outermost edge of the planar opposite end portion is notched inwardly toward the midsection to receive the hooked end of another strap element when two such elements are disposed oppositely for face-to-face engagement with each other and with their concave midsections abutting an arcuate area of the pipe.          In such complimenting disposition of the two strap elements, when each hooked tab is brought into the notched edge of the other strap element and the opposing planar opposite end portions are squeezed together, the pipe becomes effectively clamped to the channel member.

Abstract: Abstract of the Disclosure A wheel alignment measuring system for measur-ing front wheel toe including a laser beam light projector mounted on a front wheel of a motor vehicle which pro-jects a beam of light onto a pivotally mounted front mirror on the projector which oscillates back and forth through a ten degree angle about a reference line.  The beam of light reflected from the oscillating mirror swings ten degrees on either side of a central reference beam line, and during its swing the beam strikes a fixed roof mirror mounted on the opposite front wheel of the vehicle.  The thus reflected beam sweeps back and forth across the light projector and is successively intercepted by each of a pair of closely spaced photocells on the light projector, the cells being equally spaced on opposite sides of the reference beam line.  The cells develop signals when they intercept-the light beam which signals control an up/down counter through a flip-flop.          The time interval required for the moving light beam to fall on a first cell, sweep in one outward direction and return in the opposite direction to the second cell is compared with the time interval required for the beam to continue its sweep from the second cell in said opposite direction and return in said one outward direction to the first cell.  Such comparison is stored by the counter as a binary difference signal.  A digital/analog converter converts the binary difference between these time intervals into a voltage which represents the total toe angle between the front wheels.  The toe angle of the projector-mounting front wheel is obtained in a similar -1a-manner by sweeping a rearwardly directed light beam across a fixed roof mirror on the rear wheel that is directly behind said front wheel.  In the preferred embodiment, the direction or "sense" of the oscillating light beam is obtained by employing two photocells on opposite sides of a reference line so that the paired cells intercept the beam in one order on an outward sweep and in the opposite order on a return sweep.  In a modified embodi-ment, a single cell replaces the paired cells, and a switch, which is operated by a cam on the motor shaft that swings the mirror, provides signals to a circuit which determines the direction of beam swing.                           -1b-
